we have 1 of the glow warm ventless gas wall heaters in the living room, which all the rooms are pretty much connected to, and it does not need power, so we were set with heat, and managed to keep it around 71-72* nights, but it never shut off for very long...

what do you do with the screw driver to those cans? I have an old type nozzle that fits the can, but I lost the end cap to it, so I only use it if I have to.. I would have gotten it if I knew where I last put it .
